We are applying Reaction Mechanism Generator (RMG) to detailed and comprehensive characterization of JP-10 combustion chemistry. JP-10 is a large synthetic fuel with complex high temperature decomposition chemistry for which detailed characterization has been considered intractable; and RMG is a computer program that we developed for automatic construction of predictive kinetic models. In this paper, we present initial results from applying RMG to JP-10 combustion. After considering over 25,000 possible species and more than 1 million possible reactions, we have developed a highly detailed JP-10 combustion mechanism that currently consists of 317 chemical species and 7,715 elementary reactions. Comparisons against existing mechanisms and experimental data in published literature reveal that this RMG-constructed mechanism establishes a new state of the art in JP-10 combustion modeling: ignition delay predictions accurately reproduce experimental observations (to our knowledge, the first detailed mechanism to accomplish this); and our mechanism provides the first detailed insight into the high temperature initial decomposition chemistry of JP-10 in the presence of oxygen, particularly down to C5 hydrocarbons. We are also developing transport property estimates for all species in the mechanism. The final result of this effort will be an experimentally validated comprehensive JP-10 combustion mechanism containing all parameters necessary for application in reacting flow simulations. |
